Title: Materials Data on K2ZnP4(HO2)8 by Materials Project

Abstract

K2ZnP4(HO2)8 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. K1+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of K–O bond distances ranging from 2.78–3.21 Å. Zn2+ is bonded to six O2- atoms to form ZnO6 octahedra that share corners with four PO4 tetrahedra. There are four shorter (2.11 Å) and two longer (2.13 Å) Zn–O bond lengths. There are two inequivalent P5+ sites. In the first P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share a cornercorner with one ZnO6 octahedra and a cornercorner with one PO4 tetrahedra. The corner-sharing octahedral tilt angles are 49°. There are a spread of P–O bond distances ranging from 1.52–1.62 Å. In the second P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share a cornercorner with one ZnO6 octahedra and a cornercorner with one PO4 tetrahedra. The corner-sharing octahedral tilt angles are 50°. There are a spread of P–O bond distances ranging from 1.51–1.63 Å. There are four inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a linear geometry to two O2- atoms. There is one shorter (1.04more » Å) and one longer (1.49 Å) H–O bond length. In the second H1+ site, H1+ is bonded in a linear geometry to two O2- atoms. There is one shorter (1.04 Å) and one longer (1.54 Å) H–O bond length. In the third H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. In the fourth H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. There are eight inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 120 degrees geometry to one P5+ and one H1+ atom. In the second O2- site, O2- is bonded in a distorted water-like geometry to one K1+, one P5+, and one H1+ atom. In the third O2- site, O2- is bonded in a 1-coordinate geometry to two equivalent K1+, one Zn2+, and one P5+ atom. In the fourth O2- site, O2- is bonded in a bent 120 degrees geometry to one K1+, one P5+, and one H1+ atom. In the fifth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one K1+, one P5+, and one H1+ atom. In the sixth O2- site, O2- is bonded in a 2-coordinate geometry to one K1+, one Zn2+, and one P5+ atom. In the seventh O2- site, O2- is bonded in a bent 120 degrees geometry to two P5+ atoms. In the eighth O2- site, O2- is bonded in a distorted water-like geometry to one K1+, one Zn2+, and two H1+ atoms.« less
